d. Installing a disk brake or rim brake Rear Wheel
CAUTION: If your bike is equipped with a rear disk brake, be careful not to damage the disk, caliper or brake pads when re-
inserting the disk into the caliper. Never activate a disk brake’s control lever unless the disk is correctly inserted in the caliper.
(1) With a cam action system, move the cam lever to the OPEN position (see fig. 8 a & b). The lever should be on the side of the wheel
opposite the derailleur and freewheel sprockets.
(2) On a derailleur bike, make sure that the rear derailleur is still in its outermost, high gear, position; then pull the derailleur body back with
your right hand. Put the chain on top of the smallest freewheel sprocket.
(3) On single-speed, remove the chain from the front sprocket, so that you have plenty of slack in the chain. Put the chain on the rear wheel
sprocket.
(4) Then, insert the wheel into the frame dropouts and pull it all the way in to the dropouts.
(5) On a single speed
or an internal gear hub, replace the chain on the chainring; pull the wheel back in the dropouts so that it is straight in
the frame and the chain has about 1/4 inches of up-and-down play.
(6) With a cam action system, move the cam lever upwards and swing it into the CLOSED position (fig. 8 a & b). The lever should now be
parallel to the seat stay or chain stay and curved toward the wheel. To apply enough clamping force, you should have to wrap your fingers
around the fork blade for leverage, and the lever should leave a clear imprint in the palm of your hand.
(7) With a through-bolt or bolt-on system, tighten the fasteners to the torque specifications in Appendix D or the hub manufacturer’s
instructions.
NOTE: If, on a traditional cam action system, the lever cannot be pushed all the way to a position parallel to the seat stay or chain stay, return
the lever to the OPEN position. Then turn the tension adjusting nut counterclockwise one-quarter turn and try tightening the lever again.
WARNING: Securely clamping the wheel with a cam action retention device takes considerable force. If you can fully close the
cam lever without wrapping your fingers around the seat stay or chain stay for leverage, the lever does not leave a clear imprint
in the palm of your hand, and the serrations on the wheel fastener do not emboss the surfaces of the dropouts, the tension is
insufficient. Open the lever; turn the tension adjusting nut clockwise a quarter turn; then try again. See also the first WARNING in this
Section, p. 18.
(8) If you disengaged the brake quick-release mechanism in 3. c. (2) above, re-engage it to restore correct brake pad-to-rim clearance.
(9) Spin the wheel to make sure that it is centered in the frame and clears the brake pads; then squeeze the brake lever and make sure that
the brakes are operating correctly.
NOTE: If, on a traditional cam action system, the lever cannot be pushed all the way to a position parallel to the fork blade, return the lever to
the OPEN position. Then turn the tension adjusting nut counterclockwise one-quarter turn and try tightening the lever again.
D (6) With a through-bolt or bolt-on system, tighten the fasteners to the torque specifications in Appendix D or the hub manufacturer’s
instructions.
WARNING: Securely clamping the wheel with a cam action retention device takes considerable force. If you can fully close the
cam lever without wrapping your fingers around the fork blade for leverage, the lever does not leave a clear imprint in the palm

(6) If you disengaged the brake quick-release mechanism in 3. a. (1) above, re-engage it to restore correct brake
pad- to-rim clearance.
(7) Spin the wheel to make sure that it is centered in the frame and clears the brake pads; then squeeze the brake
lever and make sure that the brakes are operating correctly.
c. Removing a disk brake or rim brake Rear Wheel
(1) If you have a multi-speed bike with a derailleur gear system: shift the rear derailleur to high gear (the smallest,
outermost rear sprocket).
If you have an internal gear rear hub, consult your dealer or the hub manufacturer’s instructions before
attempting to remove the rear wheel.
If you have a single-speed bike with rim or disk brake, go to step (4) below.
(2) If your bike has rim brakes, disengage the brake’s quick-release mechanism to increase the clearance between
the wheel rim and the brake pads (see Section 4.C, figs. 11 through 15).
(3) On a derailleur gear system, pull the derailleur body back with your right hand.
(4) With a cam action mechanism, move the quick-release lever to the OPEN position (fig. 8b). With a through bolt
or bolt on mechanism, loosen the fastener(s) with an appropriate wrench, lock lever or integral lever; then push
the wheel forward far enough to be able to remove the chain from the rear sprocket.
(5) Lift the rear wheel off the ground a few inches and remove it from the rear dropouts.
